------------------------------------
Summary: DUCC RM Dynamic nodepool updates
Key: UIMA-4142
URL: https://issues.apache.org/jira/browse/UIMA-4142
Project: UIMA
Issue Type: Improvement
Components: DUCC
Affects Versions: 1.1.0-Ducc
Reporter: Jim Challenger
Assignee: Jim Challenger
Fix For: 2.0.0-Ducc
We need the ability to dynanically change nodepool definitions without
restarting RM (or DUCC). Currently we can dynamically add and subtract hosts
without restarting but on add, if the host is not defined to a nodepool at the
time of last start, it goes into the "global" pool, which is often wrong.
Tasks:
- API/CLI to add / delete / rearrange a host in RM's current memory nodepool
structures
- sanity-checking and hot-repair so hot RM restart works correctly if
nodepools are statically changed, RM is restarted, and the new configuration
conflicts with the older one
- API/CLI to insure the nodepool files are kept consistent with the memory
updates.
